PENCIL POINTER.

Application filed August 26, 1924, Serial No. 734,318, and in GermanyAugust 30, 1923.

My invention relates to an improved pencil-pointer, which is combinedwith a crank for turning the cutter in the manner of the knownpointing-machines afiiiied to a table or the like, but which otters theparticular advantage to be of a more simple kind and of such small sizethat it may be conveniently carried in a waist-co-at-pocket, like theknown pointers, which latter, on being used,

are applied and turned by 'one hand, while the other hand holds thepencil in a stationary position. Such pointers of the usual kind aresubjected to the deficiency, that the point of the pencil willfrequently come to break when the fingers, which turn the littlepointing-device, but slightly swerve from the straight line which,normally, rigidly holds the pencil. To prevent such breaking of thepoint, I have combined to the said pointing apparatus a movable guidingdevice. By the aid of such movable guide all the se curities areprovided, which are offered by the known pointing machines which to beused are secured to a table for preventing the deviation of the cutterfrom the straight line.

In the accompanying drawings I have illustrated my invention. Fig. 1shows the pointing-device in side-elevation, mounted on top of a pencilto be pointed. Fig. 2 shows, how the working is performed by turning thecrank. Fig. 3 is a longitudinal section of the device taken in the planeof the pivoted crank.

a is the small pointing-device of the usual type, having a conical boreto fit the top of the pencil, a shoulder Z) is formed to said device andthe usual pointing-knife is fixed to said shoulder by means of a screw0. At the opposite side of said device a, another shoulder 6 has beenprovided Within a passing groove (Z of which a crank f is pivoted. toturn on the pivot g. The said crank f has an extension beyond the pivotg, the purpose of which extension is, to permit the said crank to beslightly raised, as indicated by dotted lines, for allowing the fork 7bof the extension 2' to find a resistance on the pencil. The pencil willaccommodate itself to the actual pressure applied on turning the saidcrank. The said fork hvtor clasping the pencil corresponding the actualpressure applied, will keep the point of the lead in permanent, straightline with the revolvingpointing-device a, and, thereby, prevent anytendency of breaking or hurting the point of the lead.

I claim asmy invention:

An improved pencil-pointer, comprising a cutting-device of a knownconstruction, a removable cutting-knife secured within the bore of saiddevice, a groove cut into the length of said device, an arm pivoted toturn within said groove, an extension formed to the rear of said arm, afork secured to the rear of said extension for clasping the shaft of thepencil, and a crank secured to the front of said arm for turning thesaid cutting-device, substantially as set forth.

In testimony whereof I have aflixed my signature.
